The electronic structures of mono- and dinuclear metallocenes NiCp2 and Ni2Cp3+ have been calculated by means of CNDO method. The bonding in both the two compounds have been analyzed and discussed from the compns. of wave functions and d. contour maps and a comparison between NiCp2 and Ni2Cp3+ have been carried out. The characters of chem. bonds in both NiCp2 and Ni2Cp3+ have been indicated.

Key words: CYCLOPENTADIENE P, CNDO APPROXIMATION, ENERGY LEVELS, ELECTRONIC STRUCTURE, TRANSITION METAL COMPOUND, METALLOCENES, MOLECULAR ORBITAL THEORY, NICKEL COMPLEX, DINUCLEAR COMPLEX, SANDWICH COMPOUNDS
